test: Add E2E test coverage for shader IO This provides much more complete coverage than what we have in the unit tests. We now test: - All builtins, for all stages, both struct and non-struct - Multiple location attributes for vertex and fragment stages, both struct and non-struct - Mixing builtins and location attributes, whilst mixing struct and non-struct - A few "interesting" cases of IO structs being shared between different functions, stages, and with an SSBO variable There are 7 skipped tests for MSL due to two different MSL bugs which will be fixed in upcoming patches.

writer/spirv: Add Flat decoration to integers Vulkan requires that shader inputs/outputs that are integers must be decorated with Flat.
